Abstract

PURPOSE: To perform satisfactory combustion by jetting the total required fuel jet amount when it is not more than a first jet amount, that is, under a low load, and jetting the fuel jet amount while being distributed to intake and compression processes when it is less than a second and not less than a third jet amount, that is, under a medium load.
CONSTITUTION: In a control unit 20, a fuel pressure detected by a sensor 27, an engine speed obtained from a crank angle signal of a sensor 29, accelerator opening angle detected by a sensor 30, etc., are input to compute a fuel jet amount. When the required fuel jet amount is not more than a first jet amount which is a sum of a minimum compression process jet amount for an ignition plug 65 enough to form ignitable air fuel mixture and a minimum intake process jet amount enough to propagate frame, a fuel jet valve 5 is controlled such that the total amount is jet during compression process. When the required jet amount is not less than a third jet amount which is less than a second jet amount enough to form an even air-fuel mixture and not less than the first amount, the total amount is jet while being distributed to the intake and compression processes. Satisfactory ignition and combustion are thus performed.
